Now I'm trying to binary optimization using GA tool,

I saw 'doc GA' that is support by MATLAB, but there are only use function handle like 'y=@(x) x+1'.

So, I want to know that can use .m file for object function in GA tool.

And can you tell me an example of GA tool used with Finie element method?

in 'doc GA', I can't found that example.

I think it will probably help me for use GA tool.

Please report the MATLAB version you are using, such as R2019a. It makes a difference, because, for example, the Optimization app has been removed from the latest MATLAB versions.

Please also explain what you mean by "GA tool." Do you mean the Optimization app, the thing you get by running the command optimtool? Or do you mean the ga command at the MATLAB command line? Or do you mean the Optimization app that you get by running gatool?

To answer your question, yes of course you can use a .m file as a fitness function for ga. For an example, see Minimize Rastrigin's Function, which uses a .m file representing Rastrigin's function as the fitness function.

I know of no example using ga to optimize a finite element method computation, sorry.
